The flowers that bees in my area like are anything in the daisy family cosmos, sunflowers. They also like pentas (they can only reach the pollen, long tongued bees and butterflies can reach the deep nectar), lavender, false heather, lantana, herbs in bloom like sage, basil, fennel, onions, cilantro, corn tassels (they like the pollen), vervain, verbena, single zinnias, bee balm, calendula and marigolds. They cannot see the color red. They like flowers that are small and have a landing pad and sweet fragrance. Roses, orchids, foxglove, snapdragon, fruit and nut trees, borage, echinacea. They also like cover crops like buckwheat and clover. Squash, pumpkins, cucumbers are pollinated by squash bees. You want to provide flowers that bloom for a long time and provide habitat as in bee houses for solitary bees, trees and shrubs for shelter.
Many of the plants that bees like are self seeding, so if you don't want them to go to seed, you will have to cut the seed heads off before they disperse. I take out fennel every year and start over. I do let nasturtiums, perilla and basil reseed. They are not that hard to kill. Vervain and milkweeds, I took out of the garden because they are aggressive and they are hard to get rid of. I plant a variety of lantana that is seedless so it provides nectar without pollen. The bees come for the tassels of corn and if I time it right I can have corn planted for most of the year.
The plants that I get the most visits in my gardens are penta, alyssum, false heather, basil, Jamaican oregano, orchids, roses, citrus trees when they are in bloom, palms in bloom, cilantro, onions in bloom, cosmos, sunflowers, and zinnias. If lettuce and cabbages are allowed to bloom, the bees like them too.
Happy gardening in Hawaii. Gardens are where people grow.
